ABSTRACT:
A method and apparatus for storing staggercasted content includes encoding a set of signals representing content. The set of signals is capable of being decoded to produce a corresponding set of decoded signals, each decoded signal having a quality different from the qualities of the decoded signals corresponding to the other encoded signals. A composite signal comprising the set of encoded signals, staggered in time, is generated. The set of encoded signals is extracted from the composite signal. Errors in the set of extracted encoded signals are detected to produce a subset of available extracted encoded signals which are not erroneous. A content representative signal at a selectable desired quality is decoded. The decoded content representative signal is then stored in a storage device.
